Bjorn (undead)

Bjorn was a Danish man who was, during the mid-880s, believed to be an undead prophet. He was buried at a Christian cemetery in the Danish portion of Mercia, and he would come up from under the dirt whenever Eirik the Skald offered him sacrificial blood. In 884, he prophesied that Aethelwold Aetheling would become King of Wessex, and that Uhtred of Bebbanburg would become King of Mercia.
